Overview
Gas engineers evaluating job management software consistently encounter three names: Jobber, ServiceM8, and Tradejoy. All three handle the core of a field service business — scheduling, customer records, quoting, and invoicing — but they take different approaches and have meaningfully different strengths.
This comparison focuses on what matters most to gas engineers in the UK: ease of use on mobile, certificate management, customer communication, and value for money. We're not paid by any of these companies — this is an honest assessment based on product capabilities and common feedback from trade users.
Jobber
Best for: Gas engineers who want a polished, reliable platform with excellent mobile UX and strong customer communication features.
Strengths:
- Industry-leading mobile app — clean, fast, and reliable on-site
- Excellent automated customer follow-up (texts and emails after jobs, quote reminders)
- Strong two-way client messaging
- Clean, professional invoices and online payment links
- Solid Xero and QuickBooks integration
- Comprehensive scheduling and dispatch features for teams
Weaknesses for gas engineers:
- No built-in UK gas certificate generation (CP12, commissioning certificates). You'll need Gas Engineer Software or similar alongside it
- Pricing in USD, which fluctuates against sterling
- Core plan starts around £35/month; full feature set requires £139/month+ for teams
ServiceM8
Best for: Apple ecosystem users who want a feature-rich mobile-first platform and don't mind a learning curve.
Strengths:
- iOS app is arguably the best in the category — extremely capable on iPhone and iPad
- Strong asset tracking (useful for tracking appliance history at commercial sites)
- Detailed job forms that can capture gas safety check data
- Good client-facing features including SMS updates and online booking
- Automated service follow-up reminders
Weaknesses for gas engineers:
- Android app is weaker than iOS — a significant disadvantage if your team uses Android devices
- No built-in UK gas certificate generation
- Pricing based on job volume rather than users, which can be unpredictable for growing businesses
- Australian company — customer support hours and understanding of UK-specific compliance requirements can be limited
Tradejoy
Best for: Gas engineering businesses that want to automate customer communications and reduce the admin burden of handling enquiries.
Strengths:
- AI agent handles inbound enquiries autonomously — qualifies jobs, sends quotes, and books appointments without the engineer needing to respond to every message
- Works across SMS, WhatsApp, and email — meets customers where they already communicate
- Significantly reduces the time engineers spend on phone calls and message management while on site
- Clean mobile experience for scheduling and invoicing
- Built specifically for the UK trade market
Weaknesses:
- No built-in gas certificate generation — certificate management requires a separate tool
- Newer platform than Jobber or ServiceM8 — fewer third-party integrations currently
- Best value for businesses with significant inbound enquiry volume

Verdict
If you want the most polished all-round platform: Jobber. Best mobile app, best customer communication, excellent invoicing. Pair with Gas Engineer Software for UK certificate management.
If you're on iOS and want the most feature-rich mobile experience: ServiceM8 is excellent — particularly for commercial work with asset tracking needs. Less good on Android.
If reducing admin and automating customer communication is your priority: Tradejoy's AI layer handles enquiry management in a way neither Jobber nor ServiceM8 does. Particularly valuable for gas engineers who miss enquiries while on site or who want to reduce time spent on phone calls.
For gas certificates: All three require a separate tool. Gas Engineer Software (£15–£25/month) or Commusoft (£79+/month) fill this gap. If you want certificates built-in, Commusoft remains the specialist choice.
